Since a lot of newer airsoft guns are shooting over 325 right out of the box, a heavier bb is needed. The BioShot .28g is that bb. With the same high precision as our other biodegradable bbs the .28g will fly straighter longer at a higher FPS. We recommend trying our .25g bb first for stock guns. Then if you are having issues with uncontrollable hop-up or want to tighten your groups then move up to our .28g. Every 5000 rounds come in a UV-resistant re-closable bag. This gives them a longer shelf life along with the convenience of a re-closable bag so your bbs end up where you want them instead of on the floor.
